SPECIFICATION forming part of Letters Patent No. 415,003, dated November12, 1889.

Application filed May 24:, 1888. Serial No. 274,983. (No model.)

To all whom it may concern:

Be it known that I, MARTIN S. STARK- WEATHER, a citizen of the UnitedStates, residing at Boston, in the county of Suolk and State ofMassachusetts, have invented certain new and useful Improvements inHorseshoe- Pads, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to improvements in pads or cushions of the kindused in connection with metal shoes and adapted to be fastened in placeby the nails which secure the metal.

It pertains more particularly to pads or cushions intended for use uponthe front hoofs, although the use is not limited to such application.

Figure 1 is a bottom plan view of a pad embodying my improvements. Fig.2 is a top view of the same. Fig. 3 is a side view showing the pad andmetal shoe in place upon the hoof. Fig. 4. is a longitudinal section onthe line so, Figs. 1 and 2. Fig. 5 is a cross-section on the line y y,Fig. 1. Fig. 6 is a bottom view of a modified form.' Fig. 7 is a topplan view of the same. Figs. 8 and 9 are respectively a longitudinal anda cross section on the lines a1 and y y', Fig. 6. Fig. 10 is a face viewof another modified form of pad. Fig. 11 is a section on line y2 y2,Fig. 10. Fig. 12 is a section on line 002 002, Fig. lO.

II the drawings the metal shoe is indicated by The rubber pad or cushionis formed with a flat thin base part having its outer lineward-extending arms B B.

conform substantially to that of the shoe, there being a front curvedpart B and rear- Through these iiat thin parts B B B are passed nails,which fasten the metal shoe A in place. With them there is formedintegrally a calk or comparatively large, strong, downwardly-extendingrubber projection, (indicated as a whole by C.) It consists of a main orbase part c, extending from one side part B to the other, a projection oat the front having its longitudinal lines arranged transversely of thepad as a whole, and a second transversely-arranged projection ordownwardly-extending rib c2, these and the part c being bounded by acontinuously vertical wall or shoulder C3, which fits squarely againstthe inner edge of the metal shoe. Between the projections or ribs c c2there is formed an aperture D, which in the forms shown in Figs. 1 to 4extends entirely through the pad, The side walls of this aperture at d dare preferably beveled or tapered, so as to avoid the forming of sharpcorners, that would be liable to rapid wear. The ribs or projections cc2 provide the toe calk or calks, by which the foot of the horse has afirm grip upon the ground and slipping forward or backward is prevented.Lateral slipping is prevented by the parts at c4 c5.

By providing the parts just described-that is to say, by having acomparatively deep recess or a through-aperture at these placesthe pador cushion can be caused to engage with the corners orupwardly-extending parts of stones or other projections in the road-bed,and where the road-bed is comparatively smooth the gripping is attainedby the calks c c2 c4 c5, one preventing slipping in one direction andeach of the others in another.

I am well aware of the fact that heretofore use has been made of rubberpads with iat thin base parts, each lying between the metal shoe and thehoof, together withy toe-calks, and I do not broadly claim rubber padsas my invention.

It is not necessary to carry the depression between the ribs c c2entirely through the pad, as some of the features of advantage arepresent, even if it consists of a groove or recess, so long as strongcalk-ribs are provided. Thus in Figs. 6, 7,8, and 9 a construction isshown in which'the parts c c2 consist of such ribs, the base part beingimperforate, as shown in the sectional gures 8 and 9.

When the aperture D is carried entirely through the rubber, it acts topermit the air to pass through for the purpose of ventilating the underside of the hoof.

In order to increase the frictional grip of the pad or cushion upon theroad-bed, I prefer to cover the under surface with a layer ofreticulatedmaterial-such as strong canvaswhich increases'the hold of thehoof. The rear edge of the base/part c of the calk is curved, as shownin plan view, so as to provide two comparatively sharpbackward-extending spurs or projections E E. These act to insure a iirmholding of the heel part of IOO the hoof, especially Vguarding against abackward slipping, this holding act-ion resulting from the backwardcurve of the edge and from having it and the edge c3 terminate in saidspurs or projections.

In the pad shown in Figs. 10, ll, and 12 there are two apertures D and asupplemental projection c2.

That I claim is- 1. A rubber pad or cushion fora horseshoe, having thefiat thin base partB B B', extending around the foot and receiving theshoenails, the web c, proj eeting below the part B B and extending fromthe front part of the foot to a line behind the center and terminatingin a concave rear edge in front of the heel, and the transverse ribs c'c2, extending down from the web c, and each being beveled or V'shaped insection and extending from side to side, with the ytransverse recessesbetween them, said ribs lying under the central part of the foot,substantially as set forth.

2. A rubber horseshoe-pad having the thin base part B, extending aroundthe foot and adapted to receive the metal nails, base-web c, extendingacross the foot, with the series of transverse ribs c c2 running fromside to side under the toe, and the through-apertures be tween saidribs, whereby Ventilation is provided under theibase-web c, the webterminating in the rear curved edge c8 at a distance in front of theheel ends B B', whereby the rear part of the foot is exposed,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
